As an AI language model, I don’t have personal experiences, but I can provide you with an example of an engineering log lesson with gears:

Project: Designing a Gear System for a Conveyor Belt

Objective: To design a gear system that will efficiently transfer power from the motor to the conveyor belt.

Materials: - Motor with a power output of 2 horsepower - Conveyor belt with a length of 10 meters and a width of 1 meter - Gears of various sizes - Bearings - Shaft

Procedure:

  1. Determine the required speed of the conveyor belt. In this case, the conveyor belt needs to move at a speed of 1 meter per second.

  2. Calculate the required torque to move the conveyor belt. The torque required is dependent on the weight of the load being transported. In this case, the load is assumed to be 1000 kg. The torque required is calculated as follows:

Torque = (Load x Distance)/Time Torque = (1000 kg x 10 m)/1 s Torque = 10,000 Nm

  1. Select the appropriate gear ratio. The gear ratio is the ratio of the number of teeth on the driven gear to the number of teeth on the driving gear. The gear ratio is calculated as follows:

Gear Ratio = Driven Gear Teeth/Driving Gear Teeth

In this case, a gear ratio of 10:1 is selected.

  1. Calculate the required size of the driving gear. The size of the driving gear is dependent on the torque required and the gear ratio. The size of the driving gear is calculated as follows:

Driving Gear Size = (Torque Required x Gear Ratio)/(2 x π x Motor Power)

Driving Gear Size = (10,000 Nm x 10)/(2 x π x 2 hp) Driving Gear Size = 318.31 mm

  1. Select the appropriate driven gear size. The size of the driven gear is dependent on the gear ratio and the size of the driving gear. The size of the driven gear is calculated as follows:

Driven Gear Size = Driving Gear Size/Gear Ratio

Driven Gear Size = 318.31 mm/10 Driven Gear Size = 31.83 mm

  1. Select the appropriate bearings and shaft size. The bearings and shaft size are dependent on the size of the gears and the torque being transferred.

  2. Assemble the gear system and test for efficiency and effectiveness.

Conclusion:

The gear system was successfully designed and assembled. The conveyor belt was able to move at the required speed of 1 meter per second and was able to transport the load of 1000 kg. The gear system was efficient and effective in transferring power from the motor to the conveyor belt.
